To all whom it may concern:

a citizen" of the United States,and resident of Seattle, in the countyof King and State} of Washington, have invented certain new and usefulImprovements in Attachments for Miter-Boxes, 'off which the following isa clear and exact specification.

attachments for .miter boxes and the object of this improvement is toprovide an attach-.

ment that mayreadily be secured to the vertical side of a miter box and:quickly and easily adjusted into variousf anglesof divergence from saidvertlcal slde to support a piece of timber in an inclinedposition withrespect to both the ertical side and s the horizontalbottom ofthe "miterbox so that the piece of timber may bemiter cut on an angle with respectto all of its side surfaces. s

When a piece oftimber of rectangular shape is laid fiat on thehorizontal bottom side of a miter box and cut at an angle by turning themiter saw at other than right angles to the yerticalsideof the box, the

plane of the cut surface of the timber will be at right angles to theplane of the top and a bottom surfacesof the timber, and at other thanright angles to the two side surfaces of the piece of timber. If thepiece of timher is turnedso that none ofits sidesurfaces are parallelwith'the plane of thebottom of the miter box and then cut with the sawat other than right angleslto theback of. the box, the plane of the mter cut end; will not be at right angles;to any of the side surfacesofthe piece of timber.

The attachmentfdisclosed in this application is adapted tosupport apiece of timber in an inclined position so that its side surfaces arenot parallel with the bottom side of the miter box respectively. n

The invention consists in the novel con struction of an attachment ofthe class de scribed and theadaptation and combination of the attachmentwith a miter box as will be more clearly hereinafter describedandclaimed.

be sawed. s t a i s s 'The side of the box7 asherein shown is formed ofcorrugated metal but itis obyious thatthese "attachments will workequally well on a box having a straight, non-corrue gated vertical side.

The box 5 is providedwith a transverse bar 10 pivoted as at 11andadapted to sup port two, upright saw guides 12 and 13 wherein ismounted a reciprocable saw 1e that may beturned at other thanright an:gles to the side 7 of'the box, all of the above a parts being ofwellknown standard con struction. s j 1 a: This invention contemplates theprovision of a pair of attachments that are adapted] to lbesecured totheside 7 of the miter box on each side of thesaw andadjusted into variousangular positions with respect to theside 'Zto form a support and guidefor be sawed. t s

The attachments each comprise a flat plate piece oftimber Sthat is to i15 that isprovided near each end with hook shaped members 16 that areadapted to hook t over the top edge of the side 7 as more thereto bysetscrews l7.

clearly shown in Fig. 2, andtobe secured The rear sideof theplate15lispreferably recessed for the reception of the down wardly projectingends 18 of the hook memhere 16 whichfextend entirelyj across the plates15 and are secured theretoby screws The plates 15 are supportedbytherhook *mexnbersldin such a positionthatthey will just clear thebottom 6 of the .rniter I. box,and such plates 15 are providednear theirbottom edges with holes 21 wherein are disposed screws 22 that arethreaded through the depending portions 18 of the hook members and areadapted to be screwed against the vertical side 7 of the miter box tosupport the lower edgeof the plate 15 at a desired distance from theside 7 One end of each of the plates 15 is preferably beveled as at 23so that it will clear the saw 14 when the saw is turned at an angle tothe side 7.

The beveled ends 23 of the plates 15 are also preferably cut at an anglethat is inclined away from the saw 14 from top to bottom of the platesso that when the bottom edges of the plates 15 are moved out wardly byturning the screws 22 the lower portions of the beveled ends 23 will notinterfere with the saw 14. The plates may be made in pairs for the rightand left side of the miter box respectively, or such plates may beprovided with bevels 23 on both ends in an obvious manner so they willbe interchangeable with respect to the two sides of the box.

The front surface of the plates 15 are preferably roughened or serratedso that a piece of timber will have less tendency to slide thereover andthe bottom table 6 of the miter box is usually roughened in a similarmanner.

This device is especially useful in cabinet making and pattern shops,and in the interior finishing of boats where pieces of timbers are oftenplaced together in various inclined positions.

When the screws 22 are not in engagement with the side 7 but arewithdrawn to permit the depending end 18 of the hook members 16 to hangin a vertical position then the plates 15-will be parallel with the sidewall 7 and themiter box may be used in the ordinary manner withoutremoving these attachments therefrom.

In operation, if it is desired to cut the piece of rectangular timber 8on an angle with respect to two of its sides it may be placed on thebottom of the box 6 with one side in contact with the vertical plates 15and cut in a plane at right angles to the top and bottom surfaces of thetimber 8 and at other than right angles to the side surfaces of suchtimber.

If, however, it is desired to cut the timber S at an angle other than aright angle to all ofitssides the screws 22 may be screwedinwardlyagainst the plate 7 far enoughto give the plates 15 the desiredangle and the piece of timber 8 may be held securely against the plates15 and sawe'd.

It is obvious that changes in theform of of the attachments hereindescribed may be resorted to within the scope of the claims.

What I claim and desire to protect by Letters Patent is 1. Thecombination with a miter box having a horizontal bottom and side wallsat right angles thereto, of plates connected at their top edges with thetop edges of said side walls and means for moving the bottom edges ofsaid plates away from said side walls. 2. The combination with a miterbox having a horizontal bottom and a side wall at right angles thereto,of a plate having hooks on the top edge thereof that hook over the topedge of said side wall, and screws in the bottom edges of said platesthat are adapted to engage the lower portion of said side wall tosupport said plate at an angle with respect to said side wall.

3. The combination with a miter box hav ing a horizontal bottom and aside wall at right angles thereto, of a plate having hooks on the topedge thereof that hook over the top edge of said side wall, and screwsin the bottom edges of said plates that are adapted to engage the lowerportion of said side wall to support said plate at an angle with respectto said side wall, said plate being cut at an angle and beveled on oneend to clear the saw of said miter box.

4. An attachment of the class described comprising a plate having abeveled inner end that is cut on an incline from top to bottom, a strapsecured to the rear side of said plate adjacent each end thereof,rearwardly directed hooks formed on the upper ends of said straps, andscrews adapted to screw through said straps, said plates being providedwith recesses wherein said screws are disposed.

5. An attachment for miter boxes comprising a plate having an inner endthat is cut on an angle from top to bottom thereof and is beveled onsaid inner end to clear a saw said plate having grooves formed in therear side thereof, straps disposed in said grooves and secured to saidplates, outwardly directed hook portions formed on the top ends of saidstraps, set screws provided in said hook portions and screws threadedthrough the lower ends of said straps the said plate being provided withrecesses wherein said screws are operatively disposed so that they willnot project outwardly from the plane of the front surface of said plate.
